IMPROVEMENT IN DEVICES FOR SECURING THE NOZZLES 0R NECKS 0F OILEIiS, &c.

Specification forming part of Letters Patent No. l 51,775, dated June9,1874; application filed November 1, 1873.

To all whomV it may concern:

Be it known that l', CHARLES HENRY HALL, of Brooklyn, in the county ofKings and State of New York, have invented a new and useful .side totherubber bushing ofthe nozzle, thus constituting a secure fastening forthe nozzle, but permitting its ready detachment by turning it out.

lu the accompanying drawing, Figure l is an elevation of an oiler, therubber body being shown in section to exhibit the construction of theneck, and the metallic bushing being shown in elevation. Fig. 2 is avertical scction ofthe upper portion of the'same. Fig. 3 is an elevationof the nozzle with the metallic bushing of the neck shown in section andthe rubber body omitted.

In the illustration given in Figs. 1 and 2, A represents the body of anoiler, made of soft rubber, tempered so as to give it the necessarylresilience, and cured at a high temperature to adapt it to resist oil. Bis a bushing, of soft rubber, applied to the base of a metallic nozzle,O, and adapted to iit within the sheetmetal neck D, the spiral bead d inwhich is embedded in the rubber in the act of inserting the nozzlewithin the neck, so as to form a screw-thread. The formation of the beadon the internal surface of the metallic neck D produces on the outside agroove, which adapts the neck a of the rubber body A to4 cling securelythereto. E represents a flange or collar, which limits the entrance ofthe nozzle or stopper, and may be milled on its periphery to facilitatewithdrawing and inserting it.

Many advantages will accrue from the use of rubber as a material for thebody of the oiler. It may, if desired, be coated on the in side withcement; but, as already stated, the rubber itself can be so cured as tomake it impervious to oil. The article may be made of either white orblack rubber. The resilience ot the material adapts the vessel to befilled by atmospheric exhaustion on the same prillciple as a syringe,thus avoiding the necessity ot' taking out the nozzle. It is moredurable than a metal can, and is not liable to be dented or injured by aslight blow. Rubber being a .poor conductor of heat, the oil does not asreadily congeal in. it in cold weather.

The invention is equally adapted for selfoilers, as my deviceconstitutes au excellent mode of forming the required air-tight joint inthe neck.

The following is claimed as new:

The oiler consisting of the body made of resilient rubber, incombination with a metallic spirally-threaded neck, and a bushing ofsoft rubber surrounding the tubular stopper, as and for the purpose setforth.

1n testimony of which invention I hereunto set my hand this 14th day ofOctober, 1873.
